You're right. It's a linking verb.

Thanks :)

You're welcome.

Yes, you are correct. "Remained" is a linking verb in this sentence.

A linking verb, also known as a copular verb, connects the subject of a sentence with a word or phrase that describes or renames it. In this case, "remained" connects the subject "the interviewer" with the adjective "speechless."

To identify linking verbs, you can ask yourself if the verb describes a state of being or if it connects the subject with a description or identification. Other common linking verbs include "be," "seem," "appear," "become," and "look."

It's important to note that linking verbs don't show a direct action being performed, like action verbs do. Transitive verbs are those that require a direct object to complete their meaning, while auxiliary verbs are used to form verb tenses or to provide additional information in a sentence.
